Is it best practice to have a canonical tags on all pages
-
The website I'm working on has no canonical tags. There is duplicate content so rel=canonicals need adding to certain pages but is it best practice to have a tag on every page ?
-
ColesNathan,
Have you seen what Google has to say about canonicals? https://support.google.com/webmasters/answer/139066?hl=en
You might find it helpful. They list reasons why you might want to use a canonical tag including those identified above and a few others, for example, for letting Google know your priorities when it comes to crawl budget and SERP display.
Canonicals can also help undermine plagiarism. If scrapers leave your self-referencing canonical intact, it will tell Google you are the originator of that content and consolidate link signals into your URL.
-
Correct, I would usually advise adding in a self-referencing canonical tag to make it easier for audits and search engines to understand what the actual content is on the page.
-
Hi, thanks for getting back to me. Ok so you don't need a canonical on every page unless its required.
However, for tracking purposes it is good practice to have one set up on all pages?
Have I got that right ?

Hi there!
It is a best practice as long as you have a CMS or any system that allows you to control them. In the case of Wordpress with YOAST it is pretty easy to set up.
Why would you want a canonical on every page? This is useful when you have different campaigns and you use url parameters for tracking (the common _utm from Google analytics), and that is correctly taken care of with wordpress+YOAST.If you see that you dont need canonicals on any page, then dont use it. Just be sure that when generating parameters o duplicate content, there is a canonical.
Hope i´ve helped.
Best luck.

Best-practice URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
Best Practices for Homepage Title Tag
Hi, I would like to know if there is any update about the best practices for the homepage title tag. I mean, a couple of years ago, it was still working placing main keywords in the homepage title tag. But since the last google SERP update, the number of characters that are being shown were reduced, and now we try to work with 55 and 56 characters. That has reduced our capacity of including many keywords on the title tag. Besides, search engines are smarter now to choose the correct inner page to show in SERP. But I am wondering if the Homepage Title should have a branded orientation or should include main keywords, cause it is still working that strategy. I would appreciatte any update in this issue. Thank you!

Duplicate Title tags even with rel=canonical
Hello, We were having duplicate content in our blog (a replica of each post automatically was done by the CMS), until we recently implemented a rel=canonical tag to all the duplicate posts (some 5 weeks ago). So far, no duplicate content were been found, but we are still getting duplicate title tags, though the rel=canonical is present. Any idea why is this the case and what can we do to solve it? Thanks in advance for your help. Tej Luchmun

Duplicate Content www vs. non-www and best practices
I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess Rule for duplicate content removal : www.domain.com vs domain.com RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
Intermediate & Advanced SEO | | EnvoyWeb
RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC] The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com I wonder if this is causing issues in SERPS. If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites. -----Can you comment on whether this is a best practice for all domains?
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?0 -
Domain Name Change - Best Practices?
Good day guys, We got a restaurant that is changing its name and domain. However they are keeping the same server location, same content and same pages (we are just changing the logo on the website). It just has to go a new domain. We don't want to lose the value of the current site, and we want to avoid any duplicate penalties. Could you please advise of the best practices of doing a domain name change? Thank you.

Best practice to redirects based on visitors' detected language
One of our websites has two languages, English and Italian. The English pages are available at the root level:
Intermediate & Advanced SEO | | Damiano
www.site.com/ English homepage www.site.com/page1
www.site.com/page2 The Italian pages are available under the /it/ level:
www.site.com/it Italian homepage www.site.com/it/pagina1
www.site.com/it/pagina2 When an Italian visitor first visits www.mysit.com we'd like to redirect it to www.site.com/it but we don't know if that would impact search engine spiders (eg GoogleBot) in any way... It would be better to do a Javascript redirect? Or an http 3xx redirect? If so, which of the 3xx redirect should we use? Thank you0
